in the manufacture of paper boxes, the

paper blanks for forming the boxes, or

parts Of boxes, are bent or folded into the shape desired, thel fldingi lines being determined by grooves or scores in the blanks, as, for instance, disclosed in applicants application 1909. .The mechanism herein disclosed is particularly ldesigned to feed and cut from a continuous Web blanks or flange strips which may be embodied with other elements into a box, yas disclosed in the aforesaidapplicat-ion, and this application is a division of'. the application above identified.

When the blanks are cut from a continu-A ous Web of material and folded into an article by separate mechanism, it is important to feed the material accurately into cutting position and to cut the blanks therefrom at a delinitepoint so as to produce a blank of predetermined shape and size, and one which lWill efliciently coperate with such ,niiiiihanism as may thereafter act thereupon.

Serial' No. 492,029, filed April 24;,

lThe mechanism herein described is spe cially designed. to produce paper' blanks from continuous material, said blanks being adapted foiifi'irther manipulation; but it is obvious that the 'herein .described mecha- .nism and the elements thereof are not limited to the particular application specied, n but may be employed Wherever useful.

.` In the present lembodiment acontinuous .web of paperhcardboard or other material suitable to for'iii'thefliange of box is provided with scarfed edges and with longitudinal scores orlineslwhich correspond 'with the folding lines of thev blank. Said scarfs "and scores are preferably provided .by means of the devices disclosed in the prior application lieieinb'efore referred to. .Preferablythese scores are foi'iriiinumbenand ,105, y,extend parallel to each other' along' the upfas ' firmly grip the latter between the feed roll-l per surface of the web. The web is indi! cated at 1 and the Yscores at 2, the scores bei? v ing formed preferably by removing 4the ma;

terial of the web on one side, thus nreserv- 5 ing the smooth surface of the opposite side,

as set forth in the application above identified. Prepared as thusdescribed, the web is delivered to the mechanism which feeds it into the position at which blanks are cut therefrom.

Referring now more particularly to the drawings, 3 represents a `horizontal cross` -piece which is arranged transversely in the upper rear part of the machine and forms part 'of the stationary main frame 'and which serves as a feed table for the web feeding mechanism. The web 1 passes downwardly,

along. the concave side of a curved guide plate 4f arranged at the rear end of the "feed table and -thence horizontally forward over this table and over a cutter blade or plate 5 which is arranged upon the front edge of said table.

6, 7 represent upper and lower feed wheels or rollers which are arranged on opposite sides of the path of t-he web in a position about cent-rally between the front and rear edges of the .feed table and have their pe-` ripheries knurled or roughened so that these surfaces of the feed wheels, which engage with the under and upper sides of the horizontally moving portion of the web midway of its width, obtain a rm grip upon the same and operate to feed it reliably forward v when-the feed wheels or rollers are turned v forwardly. The lower feed roller 7 is ar ranged in a cavity formed in the upper side of the feed table 3 and is mounted on a transverse shaft 8 which is journaled in stationary bearings on the adjacent part of the frame. The upper feed roller 6 is mounted' on a transverse shaft 9 which is journaled loosely at one end in a bearingon the frame, so as tobe capable of a slight vertical oscillation to permit the upper feed roller to adapt itself to slight variations in the thickness of the paper or other stock of which Athe web is made. The upper feed roller is yieldingly held downwardly in engagement with the 'upper side of the web so as to ers and insure reliable feeding of the same. The preferred means for this puipose comprise a vertically movable bearingV 10 in against the bracket 11 inwhich eupper part of the main frame and' end ofthe rod 13 is guided. For the pur-v .pose of raising the upper roller a sufcient `distance above the lower roller to permit of 'easily pushing the web between the same` when getting themachine ready, a lifting. device is provided which preferably lcony, s ists ofa screw nutlit applied to the upper m .l threaded end of the rodand adapted to bear against the upper sidel of the bracket 11. Upon turning the screw nut 14 in one direction the` upper roller 6 is raised to clear-the space between the same andthe lower roller and permit the web to be freely inserted between these rollers and after the web has been thus inserted the screw nut is loosened to permit the spring 12 'tot press the upper 80 roller against the web and cause. the latter to be gripped between the upper` and lower feed rollers.

The two feed rollers are compelled to turn in unison by 'means of intermeshing like, gear wheels 15, 16 secured respectively to' their shafts, and an intermittent rotary forward movement is imparted to these wheels or rollersso that they `feed the web forwardly step by step by a mechanism which consists of a gear wheel 17 secured to the shaft of the lowerl feed wheel 7, a pinion 18' meshing with the gear wheel 17 and provided with a ratchet ,wheel 19, a ratchet lever 2O pivoted concentrically with the pin- 95 ion and ratchet wheel and provided with a spring pressed pawl 21 engaging with the ratchetl wheel, 'an upright shifting rod 22 connected at its upper-end with the ratchet lever 20, a transverse rock lever 23 pivoted 100 on -the lower front part of the frame and connected with the lower part of the shifting-rod .22, a rotatable kcam 24=engaging with its upper sides against a roller 25 the rock lever 23 and operating to turn the 105 ratchet lever 20, so as to turn .the web `feed rollers forwardly, and a horizontal longitudinal shaft 26 journaled in the .lower part of the frame and carrying said cam 24. The idle return movement. of thel ratchet lever 20 is 110 effected by gravi-ty but may be 'aided by a spring, if *.desired.

To permit of varying the extent of the. forward movement of the web at each step to suit the width, ofblajnk desired, lthe pinion 18 may be changed for pone offlarger org; smaller size.'v For this purpose this ypinionyy is mounted onl an adjustable support 27 having preferably the form of an arm pivoted.T to swing verticallyon the frame and held adjustably in place.. by a screw 28- on the frame passing through a segmental slot in the adjust y, ble armi'` 29 represents'the main driving shaft of y the machine which is journaled horizontally 125 and transversely in bearings on the lower centra-1 part of the main frame and which may be driven bya driving belt passing around a pulley 30 at the louter end of this shaft or any other suitable means. Motie 30 i the upper rock shaft 37and at its lower is transmitted fromthis driving shaft to the' longitudinal shaft 26 previously referred to by means of a. counter-shaft ljournaled horizontally .and transversely inI the lower part of the machine below the main driving shaft and operatively connected with the 1 latter by means of a pinion 32 on the main `shaftmeshing with agear wheel 33 on the counter-shaft and also operatively connected with thelongitudinal shaft 26- bymeans 'of intermeshing beveled gear wheels`34, 35 secured respectively te the counter-shaft and the longitudinal shaft. While 'the web is being ,fed forward to the-cmechanism where blanks are cut olf from the front end of the same, it is guided so as tobe held in place against lateral movement and insureits proper presentation to the mechanism which subsequently operates uponthe same. This guiding mechanism is constructed as follows: 36 represents a plurality of segmental guiding blades or lingers which lare arranged' infront of the curved guide-plate -l and each of which Vengages with its convex `face in a longitudinal score or groove ofthi` web. The several guiding blades or fingers are mounted on a horizon vtalrock-shaft 37 journaled transversely in 'bearingson the adjacent part of the main wardly from the lower-rock 'shaft 38,'anz

upright rock arm 42 secured tov said lower frame, which shaft is rocked by means vof zortially and transversely on the lower part connected at its upper en d with a rock ,arm 40 projecting rearwardly from one-end of end with a rock arm 4l projecting rearrock shaft and engagingwith a rotatable cani'43 on'the counter-shaft-,-and 4a spring 44l which connects a forwardly-projecting arm 45 on the lower rock shaft with part of the stationary frame. A slack or loose joint is provided somewhere in the mecha- Y, nism, wherebythe movement of the cam 43 istransxuitted to the guide blades 3G, this being preferably effected by means of a slot 1. 46 lin the upper cud of the rod 39 and receiving a pin 't-T on the respective upper rock arm 40.' During each rotation of the cam 43 the high part of the same upon-engaging 'fffthe upper right rock arm'42 causes the guiding blades or lingers to be turned backwaidly by engagement ofthe lower' end of the slot 46 with the pin 47,; When the low part of this cam is presented to the rock 'arm 42,- the spring 44 actuates the intermediane connectingr mechanism,'so 'as to Infove this rod 39 and discngage the lower end of its slot 4G from the pin 4'?4 and leave the guidoblades in their rearward position free' to be mov'd forward `by the pull of the web as the latter'is subsequently fed forward by the `rollers 6, 7. The means'for .actuating these blades or fingers are so timed that the -of the latter, but during the vforward or feeding movement of the feed rollers, the guiding blades turn forwardly in unison with the same by thepull ofthe web, thereby eliminating Ithe friction on the ,web and-` the undue strain on the latter, which otherwise wouldv be' the case if\the blades Were stationary and the feeding rollers were obliged to pull the web around the convex edges of the several blades.

ln order to hold ytheweb with its scores or grooves reliably in engagement with the conyex edges of the blades or fingers 36,

pressing means are provided which pref.- erably consist of a plurality ofvertical rollers 48 which are arranged above the 'upper edge of the curved guide-plate 4 and each of lwhich engages with the rear or unscored side of the web in line with one of the scores therein and an o p}; osingy ingi blade and is yielding erative position` by means of a vertically- 'swinging uprightv arm 49 carrying the presser roller at its 4upper endand'turning loosely at. its lowerl end on', a horizontal transverse rod 50 secured to the main frame, and a coiled springlsurrounding said rod and connected' at its opposite ends with'l said supportingr armand a supporting collar 52 adjustably secured to the rod. 4

After the web issues from the front side ofthe feed rollers 6,- 7 the same is presented to the mechanism whereby successive blanks uiding and feedl lly held in its opi which blanks or flange strips may beysubsequently assembledwith'other elements. of vaber by suitablefmechanism, as hereinbeforereferred to: y Inorder to reliablyhold placement while the fr ohtj'edgev thereof is being cut off, a -clampingzdevice is provided whichholds the'web' in .place immediately in rear of the cutting line and in front of the feedingrrollersit, `7. This clamping or holding device .islpreferablyfconstructed i as follows; 53 representen pair of clamping jaws 'which are'arranged. lengthwise above the feedftablejand lower cutter blade 'on oppositesidesoftheweb feeding rollers 6, .7 and which'-are eferably constructed from a single pieceofspring steel or other metal and haveftheir `front operativo ends turned downwardly/'fb form gripping edges or flanges.n Atf'their lrear ends these jaws are connected with fa' vertically-rocking bar 54' which-f ,is A journaledtransversely 'on the adjacentstationarypart of the machineand oscillated'byfmeans of an upright connecting iso,

By making 30 jaws of spring metal thefthrow'of the highv rod 55 connected at its upper end with an upper rock arm 56 projectingrearwardly from the rocking bar 54 and at its lower end with av lower rock arm 57 projecting l 5 rearwardly from the lower part of the frame, and a rotatable cam 58 mounted on the counter-shaft and engaging with ithe lower rock-arm 57. As the high part of the cam 58 engages the lower rock-arm 57, the

clamping jaws 53 are depressed and caused to bear downwardlyr upon the web, thereby gripping the latter between said jaws and the lower cutter blade 5, s o that the same is positively held against displacement while v that portion of the web7 in front' of the clamping jaws 1s being operated upon. When the' low part of the cam 58 is presented to thel lower rock lever 57, the clamping jaws are raised into their inoperative position owing to the preponderating weight part of the cam may be slightly in excess of that .required 'for ,bringing the, 'clampin jaws'into engagement with, .the web an thereby cause these jaws to be strained-or flexed sli htly after such engagement, there-` by enabllng this clampingdevice to adaptr` itself toy slight L variations .in the thickgis: of the 'web and reliably hold' the same in place without requiring any tineadjustment 40 rof the parts `and without liabilityfof breaking or straining the'same. l

` YAtv the end of each forwardmovement of.

the web a blank or strip is cutoff trans= versely from'the front endor edge of. they:

for accomplishing vthis is constructed. as follows59 represents a transversely fand' hori-n I zon-tally'movable carriage 'or' slidewhich isj arranged: above the lower cutter plateor,

'5 blade 5 and isf-guided on the under-side of a cross piece A60 on the adjacentstat-ionary part of the yframe.` 61 represents a circular cutter', blade or disk which is pivoted on the front side ofthe carriage so as to-be capable of'rotating in a vertical plane transversely of the machine and which coperates with the front edge of. the lower cutter blade `5 4,5 same, and the preferredl form-'of :mechanismf for severing a blank from the front edge or' end of the webwhich is projected by the feed mechanism in front of the cutting line..

The-carriage upon which this rotarycutter is pivoted is reciprocated intermittentlyl preferably by means .of a vertically swinging upright rock lever 62 pivoted at its lower* 5 end on the main frame and vconnected at versl another blank therefrom.

its upper end the cutter carriage by means fof. alink .53, a crank shaft 64 jour- 'naled lengthwise on the rframe of the niachinev parallel with the-longitudinal shaft 26 and havingthe crank `65 at its front end connected by a"connecting rod 66 withthe upright rock lever (i2-*between its upper and lower j ends and a mutilated master gear wheel6 7 secured to the longitudinal shaft 26 and meshing with a corresponding' pinion 68 secured to. the adjacentpart of the crank shaft, said'pinion being one-half the size of the master gear wheel and provided fon diametrically opposite sides with dwells or lockingfaces which are adapted to be engaged successively by the concentric dwell face ofthe master wheel and on opposite Jsides' of said dwells with toothed segments l which Vare adapted to be engaged successively by the toothed segment portion of the master wheel. By this means anintermittent rotary movement is imparted to the crank shaft-from the longitudinal shaft 2G which rotates' continuously in the same direction, each step of thisfmove'ment causing the crank vshaft 64 to makeiha'lf a turn and to move `the cutter disk-6l alternately from one side to the other lof the path of the web and causing 't-he'same to rest momentarily upon reaching the end, of the stroke in either di-l rection and before commencingthe stroke in the opposite direction. While the cut-ter disk is at rest at one end of its stroke on one `-side of the path ofthe web, the latter is fed forwardly one step or space and projected beyond the4 severing line of the cutter disk and blade a distance equal to the width of :the-blank or flange strip which is desired on the box. After the vweb has been fed-forward to'this extent by its feeding mechanism and has come to rest, the cutter disk sweeps transversely across thel web and severs a j stripvfrom 'the frontend thereof and then comes to rest momentarily on the opposite side-'of the web. The latter is now fed fori-ward another step equal to the width of blank desired, and after coming 'to rest the cutter disk returns again to the opposite side ofthe web and duringthis movement sev- Itwill' be 'notedthat by this operation of the cutter disk a blank is cut from the web during each stroke of the cutter disk in either direction. For the purpose of permitting of adjusting the relation ofthe two cutters 5, 61 for adapting the same to the particular thickness .of the web and also for taking up wear upon these cutters, the lower cutter blade or plate 5.is mounted `on ythe feed table 3, so

c that the Isame is capable of moving horizontallyl relatively vto the upper rotary cutter. This adjustment ofthe lower cutter 5 is effected preferably by means of horizontal adjusting screwsy 69 interposed between opposit@ `aids of 1t-steer edge and the adjacent stationary parts of theframe, andl after a'd- Ajustment this blade is held in position by means of clamping screws 70 passing,

through longitudinal slots in this cutter blie and' into the adjacent part of the feed ta e.

In this disclosure the feeding andcutting mechanism is shown mounted in position on a frame which is similar to the frame of the box making'` machine disclosed in the prior application above referred to,:but it Will be understood that though this is the preferred mounting and arrangement, any other eiiicient supporting device may be employed.A

By the construct-ion thus described, it Will be perceived that a mechanism isprovided which, among other results, accomplishes the objects hereinbefore referred to.

It will be noted that the foregoing description sets forth a mechanism which is well adapted to feed and guide a thin or flexible web and especially a web Ahaving thin edges such as would be provided by the scarfs hereinbefore referred yto. Thus t-he blanks which are out from' the Web have their edges non-distorted so thaty in the subsequent manipulation 'of the Web these edges.

will be in proper position."
